Review Comment:
I see that this
[call](https://github.com/apache/flink/blob/49c28f7e4bc37a9196880a6727605572476fe6a9/flink-table/flink-table-common/src/main/java/org/apache/flink/table/catalog/ObjectIdentifier.java#L89)
can return <UNKNOWN> and the catalogName is nullable in ObjectIdentifier. In
this case shouldn't we set this parameter to "".
It would be worth adding a unit test when there is an Objectidentifier
without a catalogName to ensure this case is handled properly.
